    摘要: A server provides the user's desired data without the server knowing the contents or keywords of data by using a method of searching the desired data without decrypting the encrypted data, such that the privacy for the important data of the user can be secured. Also, the present invention shortens the operation time when searching the encrypted data, such that it can prevent the degradation in efficiency due to excess operation involved in the previous existing methods based on the pairing operation.

    摘要: The present invention relates to a method of searching data for a plurality of keywords when a user encrypts the data and stores the encrypted data in an unsecured server. The user transmits the inner product value of a search keyword set to a sever, and the server compares the received inner product value to an inner product value of a stored index set. When a document for which the two inner product values are matched with each other, the server returns the document.
